Queue

Incorporation of a major contribution that allows control of running jobs through a centralized queue_manager process and control utilitiies (default: not compiled in), and a RedHat 7.0 fix.

Numerous bug fixes (including a fix for deadlock bug) and preliminary support for hetergenous clusters.

Added experimental kernel-level and user-level checkpointing
support. Kernel-based checkpointing support for Linux kernel allows
checkpoint migration (dynamic movement of running jobs) of the
interactive 'vi' editor (AFAIK a historic first) as well as simpler,
multi-process scientific applications. User-level checkpointing
works cross-platforms but requires applications to be
checkpoint-ready. This is an early development release for
experienced users who want to being experimenting with and
developing their applications for checkpointing immediately.

Replacing the older NFS protocol with a TCP/IP protocol (eventually to become TLS), beta checkpointing support, fixes for the spooling problems with the pre-releases of 1.20 (jobs now go out to network if sitting around on a compute server too long), and many other bugfixes.

Removal of problematic OS-dependent load-average code in getloadf() in queued.c and replacement with changes to queued.c to obtain load averages using getloadavg.c from GNU Emacs.
